Shift Technologies announced Tuesday it has raised $50 million via Series B funding for its car buying and selling marketplace.

Powered by its Series B funding led by Goldman Sachs Investment Partners, along with its previous Series A financing from DFJ and Highland Capital Partners, Shift offers end-to-end concierge services for vehicles of buying and selling customers.

Currently available in San Francisco and Los Angeles, the company offers free on-demand test drives and appraisals at the buyers’ or sellers’ locations and manages the complete transaction process from end to end.

According to the company, sellers are guaranteed a minimum price for their vehicle immediately after the initial appraisal is completed while also offering to track down the right car for buyers if it’s not immediately available.

“We aim to invest in companies that solve major consumer pain points by rethinking a traditional market through an inventive approach,” said Ian Friedman of GSIP. “Shift provides a unique service that is transforming the way we view car ownership. The company has flipped the classic model of buying a used car on its head by providing a superior buyer and seller experience leveraging a unique technology platform. We are excited to work with Shift as they launch in more cities across the country.”

Shift plans to utilize this round of funding to grow its team and expand into new markets, expecting to operate in more than 20 markets by the end of 2016.

“There’s a massive opportunity to modernize the pre-owned car market with a combination of technology, better economics, and a consumer-centric model,” said George Arison, Shift’s chief executive officer and co-founder. “The current options are either a significant hassle or exceedingly unfair from a price standpoint. These issues aren’t going to be solved by re-creating a car dealership online, but rather by pursuing a new model that empowers private buyers and sellers. We’re excited to partner with GSIP as we take our company to the next level.”

According to Friedman, GSIP’s plans are to help Shift grow as quickly as possible.

“We are immensely impressed with Shift’s operations and product team, who have enabled the company’s platform to scale at a rapid pace in multiple markets in California today,” Friedman said. “Our diligence revealed the exceptional feedback from customers and sellers who have depended on Shift for buying or selling their car. We are excited about the opportunity to partner with Shift to enhance the trust, transparency, and ease of the entire car ownership experience. This investment will help Shift bring that remarkable experience to buyers and sellers across the country.”
